Abstract
Apparatus for stabbing casing pipe as the casing is being run into a well bore. It includes a casing handling head arranged for grasping a generally upright section of casing pipe near the upper end thereof. The head is controllable for movement in a horizontal plane extending over the well bore and is movable vertically also. An operator platform is attached to the head for movement therewith. The platform has control means mounted thereon for operating the head, whereby an operator supported on the platform can visually observe and guide stabbing of a section of casing pipe and release the same by operating the control means. The position of the platform is such that an operator supported thereon can carry out other manipulative steps associated with the casing stabbing operation, as for example, the operation of the elevators, the pipe slings, and the like.
